Description of the Invention: [Technical Field to Which the Invention Is Along] The present invention relates to a functional film and a method of manufacturing the same. There is a = energy film which can simultaneously suppress the unevenness of coating and high transmission. [Prior Art] Various functional thin ridges have been studied previously. For example, Japanese Laid-Open Patent Publication No. 2003-53906 discloses a conductive laminated body having a surface specific resistance value of Ω/cm 2 or less, and a thermoplastic resin composition containing a thermoplastic resin and a conductive filler is sequentially laminated on a substrate. A conductive layer having a specific resistance value of less than 1 G7 Ω/cm and a layer containing a thermoplastic resin having a surface resistance of 107 Ω/cm 2 to 10 17 Q/cm 2 . However, it is disclosed in Japanese Laid-Open Patent Publication No. 2003-53906 that since carbon black is used as the conductive filler, the transmittance is lowered if the desired surface resistance is to be obtained. Further, there is a problem that optical unevenness such as interference fringes and rainbow unevenness is large. On the other hand, in Japanese Patent Laid-Open No. 2-6-95997, there is an optical laminate which is sequentially formed with a === and a hard coat layer on the transparent substrate and the antistatic layer contains the resin. The conductive fine particles are formed of a secondary particle formed of secondary particles in the electric resistance preventing layer. However, the Japanese Patent Laid-Open No. 2〇〇6 95997 shaft anti-static t-shaped (four) guide is slightly good: cohesive and coated, 'there is a decrease in the optical unevenness of the interference interference, but there is an optical fog. The problem is getting higher. On the other hand, there are the following 4 201233544 Problem 'In order to improve the transmittance or haze, if the surface resistance is high, it is applied to the second energy. The present invention is to solve the above problems and to provide a functional layer, and it is possible to achieve a second aspect. The object is to provide an unevenness such as interference fringes by coating. On the other hand, the workability is set on the resin film, and in the two layers == there is unevenness, that is, the 'resin film is often on the surface with functionality>, the surface of the wire bond layer 2 is applied, and the flattening is performed. It can be seen that 'the static bond generated by the flat easy-adhesion layer as in the prior easy-adhesive layer 2, the wire found that the electric layer adopts a conductive guide which satisfies specific conditions, and thus i has become the present invention. , :', ' = and - words' can achieve the above problems by the following methods.

By using a needle-shaped oxide fine particle in a conductive metal oxide recording, it is possible to simultaneously achieve conduction and penetration, and not, optical unevenness such as a interference ship, and suppression of coating. The coating of the functional layer on the upper layer is uneven. _ is that although the performance is achieved at the time of closing, 彳- makes sense in terms of achieving this.
